114例伴体重指数异常的寻常型银屑病患者的临床特点分析

目的 探讨114例伴体重指数(BMI)异常的寻常型银屑病患者的临床特点.方法 对397例18岁以上的寻常型银屑病患者进行问卷调查及体检,并对其中245例进行期银屑病患者的病情严重程度进行评价.计算BMI,将患者分为BMI正常组(BMI<25)与BMI异常组(BMI≥25),比较男性和女性患者中BMI≥25与BMI<25患者的年龄、发病年龄、病程、病情严重程度、家族遗传史.结果 397例寻常型银屑病患者中,114例伴BMI异常,占28.7%.男性银屑病患者肥胖发生率与女性无显著差异(P>0.05),超重发生率显著高于女性(P<0.01).男性BMI≥25组年龄大于BMI<25组(P<0.05),但发病年龄和病史与BMI<25组无显著差异(P>0.05);女性BMI≥25组的年龄、发病年龄、病史均大于BMI<25组(P<0.05).245例进行期的寻常型银屑病患者中,BMI≥25组的病情较BMI<25组严重,且在女性患者中更明显(P<0.05).寻常型银屑病患者家族史对BMI没有影响(P>0.05).结论 伴有BMI异常的寻常型银屑病患者往往年龄大、发病年龄迟、病史长、病情重,且在女性患者中更明显.     

雷达作业人员精液参数与睡眠质量分析

目的 探讨雷达作业对男性精液参数与睡眠质量的影响。方法 选取自2021年1月至2022年1月于北部战区总医院生殖中心门诊行生育体检的476例男性官兵为研究对象。根据是否近距离接触雷达微波辐射将官兵分为常规组(n=437)与观察组(n=39)。常规组官兵均为无雷达接触,观察组官兵均为雷达作业人员。记录并比较两组官兵精液参数与激素水平、睡眠情况、性激素水平。采用Pearson相关性检验分析观察组官兵各项睡眠评分与性激素水平的相关性。采用多重线性回归模型分析精液浓度的影响因素。结果 观察组官兵的精子总数、精子浓度、前向运动精子百分率、正常形态精子百分率均低于常规组,精子DNA碎片指数、精子高DNA可染性均高于常规组,但差异均无统计学意义(P>0.05)。观察组睾酮(T)水平低于常规组,差异有统计学意义(P<0.05)。观察组官兵日间功能障碍评分、匹兹堡睡眠质量指数(PSQI)总分均高于常规组,差异均有统计学意义(P<0.05)。观察组官兵PSQI总分、睡眠质量、入睡时间、睡眠障碍评分均与T水平呈负相关(r=-0.445、-0.409、-0.387、-0.429,P<0...     

慢性前列腺炎对男性不育患者精液质量影响的分析

目的探讨慢性前列腺炎对男性不育患者精液质量的影响。方法选择慢性前列腺炎伴男性不育患者66例为研究组,102例健康正常已生育男性为对照组。对其分别进行精子密度、精子活率、精子畸形率及精子DNA完整性检测。结果与对照组比较,研究组患者的精子密度、活率明显降低(P<0.05),精子畸形率及精子DNA断裂指数(DFI)明显增高(P<0.05)。结论慢性前列腺炎使男性精液质量明显降低,在一定程度上影响男性生育能力。     

少、弱精子症生殖激素水平与染色体核型改变的研究

目的探讨少、弱精子症病人的遗传因素和内分泌因素。方法收集少、弱精子症病例240例,取外周血做染色体核型分析,然后全部病人取血用化学发光法检测血清泌乳素(PRL)、卵泡刺激素(FSH)、黄体生成素(LH)、睾酮(T)水平。结果 240例少、弱精子症患者染色体核型分析中,检出39例异常染色体核型。其中染色体平衡易位3例,罗氏易位3例,随体增加4例,性染色质改变29例。在生殖激素水平的检测中,与201例染色体正常组相比,39例染色体异常组的FSH和LH值均明显升高(P<0.01),而T值明显降低(P<0.01),PRL值差异无统计学意义(P>0.05)。结论染色体异常是导致少、弱精子症发生的一个重要原因,染色体异常可能是通过生殖激素水平的改变起作用。

目的 检测进行期寻常型银屑病患者外周血CD4+CD25+调节性T细胞(CD4+CD25+Treg)的水平. 方法 选择进行期寻常型银屑病住院患者56例和健康者16例,取外周抗凝全血,采用流式细胞术方法,检测外周血CD4+CD25+ Treg的水平,并统计和分析其特点和意义. 结果进行期寻常型银屑病患者外周血CD4+CD25+ Treg占CD4+淋巴细胞的比例为(2.65±0.73)%,健康对照组为(6.11±0.93)%.两组比较差异有统计学意义(P﹤0.001). 结论 CD4+CD25+ Treg水平降低可能与寻常型银屑病免疫学发病机制有关.     

寻常型银屑病与幽门螺杆菌感染的关系

目的探讨寻常型银屑病与幽门螺杆菌(Hp)感染的相关性,观察抗Hp治疗对寻常型银屑病的临床疗效。方法选取62例寻常型银屑病患者与35例健康体检者,通过尿素13C呼气试验及Hp粪便抗原检测观察患者感染Hp情况,比较两组的检测结果。62例银屑病患者根据Hp感染情况分为治疗组(Hp阳性患者32例)和对照组(Hp阴性患者30例),治疗组给予抗Hp三联(奥美拉唑、阿莫西林、克拉霉素)治疗及外用维甲酸软膏,对照组仅外用维甲酸软膏,观察银屑病面积和严重程度指数评分(PASI)、瘙痒视觉模拟评分(VAS)及治疗总有效率。结果银屑病组Hp感染率为51.6%,健康体检组Hp感染率为22.9%,两组间比较有显著性差异(P<0.05)。治疗组与对照组银屑病患者的治疗总有效率分别为62.5%和36.7%,两组间比较有显著性差异(P<0.05),两组治疗后的PASI、VAS评分亦有显著性差异(P<0.05)。结论寻常型银屑病与Hp感染有关。对于HP感染阳性的寻常型银屑病患者,在治疗银屑病的同时进行抗HP治疗,可以提高对银屑病的疗效。

 目的 探讨白三烯B4受体(BLT1和BLT2)在寻常型银屑病患者皮损组织中的表达及与银屑病发病的相关性。方法 选取2014-11至2018-10解放军总医院第三医学中心皮肤科治疗的寻常型银屑病30例患者的石蜡组织标本为银屑病组,另选取整形外科手术切除的正常皮肤30例为对照组。采用链霉素-生物素过氧化物酶(S-P)三步法分别检测两组皮肤表皮中BLT1、BLT2的表达,使用Image-Pro Plus6.0软件系统测量每个视野阳性染色区域的平均光密度(AIOD)值。分析银屑病患者皮损与正常皮肤表皮中BLT1、BLT2的表达强度差异。结果 BLT1、BLT2在寻常型银屑病皮损组织表皮中主要表达于棘层,在正常皮肤组织中主要表达于基底层。与正常皮肤相比,寻常型银屑病患者皮损表皮中BLT1、BLT2表达均明显增强,差异有统计学意义(P<0.05)。结论 白三烯B4受体BLT1、BLT2在寻常型银屑病皮损组织表皮棘层中高表达,提示二者与银屑病的表皮过度增殖有相关性。     

寻常型银屑病患者BMD、ALP、Ca、P、TRACP-5b的检测及其意义

目的检测寻常型银屑病患者骨代谢生化指标及骨密度的情况,以了解寻常型银屑病患者的骨代谢异常状况。方法采用双能X线吸收法对48例寻常型银屑病患者(实验组)和40例健康对照者(对照组)行腰椎、股骨颈、左前臂骨密度检测;在相同条件下用贝克曼自动生化分析仪检测两组血液中ALP、Ca、P的浓度;ELSIA法检测两组血清中抗酒石酸酸性磷酸酶-5b(TRACP-5b)的浓度。结果寻常型银屑病患者血清TRACP-5b、ALP的浓度明显高于对照组(P<0.05),差异具有统计学意义;血清Ca浓度较正常对照组低,差异有统计学意义(P<0.05);血清P的浓度和正常对照组比较差异无统计学意义(P>0.05),腰椎、股骨颈、左前臂的骨密度及T值与对照组比较,具有统计学意义(P<0.05)。结论寻常型银屑病患者骨形成和骨吸收相关酶较正常人的血清水平升高,骨密度较正常人降低,说明寻常型银屑病患者骨代谢异常并已致骨量减少。血钙异常可能是寻常型银屑病骨代谢异常的原因之一,而血P在寻常型银屑病骨代谢异常中无影响。

Glutamine supplementation in vitro and in vivo,in exercise and in immunodepression

In situations of stress, such as clinical trauma, starvation or prolonged, strenuous exercise, the concentration of glutamine in the blood is decreased, often substantially. In endurance athletes this decrease occurs concomitantly with relatively transient immunodepression. Glutamine is used as a fuel by some cells of the immune system. Provision of glutamine or a glutamine precursor, such as branched chain amino acids, has been seen to have a beneficial effect on gut function, on morbidity and mortality, and on some aspects of immune cell function in clinical studies. It has also been seen to decrease the self-reported incidence of illness in endurance athletes. So far, there is no firm evidence as to precisely which aspect of the immune system is affected by glutamine feeding during the transient immunodepression that occurs after prolonged, strenuous exercise. However, there is increasing evidence that neutrophils may be implicated. Other aspects of glutamine and glutamine supplementation are also addressed.

Sex differences in neuromuscular fatigability in response to load carriage in the field in British Army recruits

Objectives

Women are resistant to neuromuscular fatigue compared to men in response to a range of exercise tasks. The sex differences in the neuromuscular responses to load carriage have yet to be investigated.

Decrease in eccentric hamstring strength in runners in the Tirol Speed Marathon

Background

The local muscular endurance of knee flexors, during eccentric work in particular, is important in preventing or delaying kinematic changes associated with fatigue during treadmill running. This result, however, may not be transferable to overground running.

Objective

To test the hypothesis that overground running is associated with eccentric hamstring fatigue.

Methods

Thirteen runners (12 male and one female) performed an isokinetic muscle test three to four days before and 18 hours after a marathon. Both legs were tested. The testing protocol consisted of concentric and eccentric quadriceps and hamstring contractions.

Results

There were no significant differences between peak torque before and after the race, except that eccentric peak hamstring torque (both thighs) was reduced.

Conclusion

Overground running (running a marathon) is associated with eccentric hamstring fatigue. Eccentric hamstring fatigue may be a potential risk factor for knee and soft tissue injuries during running. Eccentric hamstring training should therefore be introduced as an integral part of the training programme of runners.

Oxalosis in primary hyperoxaluria in infancy

Primary hyperoxaluria (PH1) is a rare inborn autosomal recessive metabolic disorder due to the deficiency of hepatic alanine-glyoxylate-aminotransferase. This deficiency results in excessive synthesis and urinary excretion of oxalate, inducing renal stone formation and deposition of calcium oxalate in the kidney, bone, myocardium, and vessels (systemic oxalosis, SO) in the most severely affected individuals. We report renal and skeletal changes in a 3-month-old girl with PH1 and SO. Intense cortico-medullary hyperechogenicity and increased homogeneous radiopacity of normal-sized kidneys suggested the diagnosis of SO. Skeletal survey showed osteopenia and characteristic symmetrical metaphyseal transverse bands in long bones, progressively becoming more dense and migrating towards the diaphysis. Multiple pathological and slowly healing fractures of the limbs occurred at the dense band level. A radiopaque rim was then observed in flat bones, epiphyseal nuclei, and vertebral bodies. Inflammatory granulomatous reaction, induced by the presence of oxalate crystals in the marrow spaces, coexisted with progressively evident radiological signs of secondary hyperparathyroidism, with partially overlapping features. The patient was treated by peritoneal dialysis and hemodialysis until combined liver–kidney transplantation. There are no previous reports of infants treated with hemodialysis for more than 2 years.     

Interventional radiology in oncology in private practice

Interventional oncology in private practice requires expert training and can be performed in a stand-alone facility for type 1 procedures in a hospital setting for type 2 and 3 procedures where subspecialized radiologists, state-of-the-art equipment, and postprocedure hospital monitoring are available. A multidisciplinary effort with oncologists, internal medicine physicians and anesthesiologists is necessary. The practice of interventional oncology requires around the clock availability, meticulous and established protocols and procedures and a financial investment. On the other hand, it is professionally gratifying because of constant technical advances and the impact on patients.
